利用生物经济学模型，我们系统地研究了钩死亡和监管不合规如何影响被不同垂钓者种群捕捞的一系列淡水鱼的管理结果。该模型结合了一个描述三种垂钓者行为的经验子模型和一个校准为五种生活史类型的年龄结构鱼类种群子模型。钓鱼死亡率的增加通常会破坏监管效力，降低社会最佳投入(许可证数)和产出监管(最小尺寸限制)，并侵蚀渔业产生的社会福利垂钓者。然而，结果与LHT和垂钓者类型有很大差异。不遵守规定的影响是孤立的，主要是在上钩死亡率低的情况下影响补偿储量低的鱼类。然而，在缺乏对努力的监管限制的情况下，不遵守规定助长了过度捕捞，并增加了避免这种情况所需的最小规模限制。德..。
Using a bioeconomic model, we systematically investigated how hooking mortality and regulatory noncompliance influenced management outcomes across a range of freshwater fish species exploited by diverse angler populations. The model integrated an empirically based submodel describing the behaviour of three angler types with an age-structured fish population submodel calibrated to five life-history types (LHTs). Increased hooking mortality generally undermined regulation effectiveness, decreased socially optimal input (license numbers) and output regulations (minimum-size limits), and eroded the social welfare anglers derived from the fishery. However, the results strongly varied with LHT and angler type. Noncompliance had an isolated effect, primarily affecting fish species with low compensatory reserves when hooking mortality was low. However, in the absence of regulatory constraints on effort, noncompliance facilitated recruitment overfishing and increased the minimum-size limit required to avoid it. De...
